I have 2 of these. The issue is that when I connect a pc to tv converter box, #1 works just fine while #2 turns the LCD screen RED in color. The same result is sent to the analog tv as well. I ordered a different model on the off chance that the box itself is faulty. I also ordered an HP ELITE8000 which is similar in design to the 7900. I am hoping the desktop itself is "faulty" in that it will not pass the correct signal from the converter. With the box removed the screen colors are correct. No video card used. All ports are on the MB. Would I be better using a simple "pig tail" that is VGA to stereo audio and composite video out/ Presuming there is a VGA signal present at the matching connector. I would prefer NOT to use a video card for the sake of the connector. Any advice welcome.
